the aim of this study was investigating some blood parameters of blue-neck male ostriches (struthio camelus) with 4 months old after feeding a diet containing 3% sunflower oil for two months. in the morning, after about 12 h of fasting, some blood samples were collected from the wing vein of ostriches at the beginning and 60 days of study in department of animal sceince arak university . the pl...

Hypothesis Silica nanoparticles can be dispersed in organic solvents (organosols) using surfactants, such as didodecyldimethylammonium bromide (DDAB). DDAB analogues prepared with lathanide tetrahalide counterions, either a high-magnetic moment ion (HoCl3Br, DDAH) or low-magnetic moment one (NdCl3Br, DDAN), are expected to produce charged particles but only DDAH-stabilized dispersions are expec...

The objective of this study was to determine the pharmacokinetic parameters of clonidine during pregnancy compared with previously published data in nonpregnant subjects. Serial blood and urine samples were collected in 17 women during mid to late pregnancy over one steady-state dosing interval to determine clonidine noncompartmental pharmacokinetic parameters (n 17) and creatinine clearance. I...

This paper presents rainfall erosivity values derived from a 7-year rainfall recording in the Cape Verde islands, Central East Atlantic. The data set consisted of 63 storm events, continuously registered in 15-min intervals. Kinetic energy of storm rainfall corresponded to established values in other tropical locations. Two algorithms to estimate erosivity, expressed as energy times intensity, ...

pcoming mobile devices capable of using multiple access networks require new approaches to build up distributed computing networks. It is a challenge to provide seamless and interesting services with these heterogeneous infrastructures. Therefore we analyze different access networks and focus on short range communication based on Bluetooth. On the basis of a typical scenario we have done some r...

We expect a numerical simulation to improve upon our first guess; typically some sort of climatology. If a model is not better than this initial estimate of the ocean state, the model provides no new information and serves no purpose. Very often in coastal regions we are interested in predicting events—episodes when the ocean state differs greatly from the climatology. The ability of a model to...

There has been recent interest in exploring the possibilities of a given amino acid sequence assuming different secondary structures in different contexts. An 11-residue segment of a synthetic protein was successfully designed that formed an α helix in one context and a β sheet in another, prompting the authors to dub it a ‘chameleon’ sequence (Minor and Kim, 1996). On a larger scale, a 56-resi...

biochemical polymorphism study is a method of determination of genetic variation. this variability could be a basis for selection and subsequent genetic improvement in farm animals. the polymorphism in the intron 1 of chicken growth hormone (cgh) gene was investigated in the iranian native fowls by using polymerase chain reaction (pcr)-restriction fragment length polymorphism (rflp) method. the...

time-delay identification is one of the most important parameters in designing controllers. in the cases where the number of inputs and outputs in a system are more than one, this identification is of great concern. in this paper, a novel autocorrelation-based scheme for the state variable time-delay identification for multi-input multi-output (mimo) system has been presented. this method is ba...

The typical objective of research is to try and identify cause-and-effect relationships. As with any research design, there are strengths and weaknesses involved in trying to achieve this objective. Some study designs are stronger than others in attempting to establish cause-and-effect associations. The task of establishing cause-and-effect relationships is challenging (Hill, 1965) and any stud...
